          <xsi:annotation>
            <xsi:documentation>Element containing the time support (or temporal footprint) of the data values.  

@isRegular indicates if the spacing is regular.
the timeInterval is the spacing between the observations, with the units being the units of the spacing.
This basically communicates the precision of the observation. If timeSupport isReqgular, and has units of 1 day, then clients should reformat output to spreadsheets and applications to day values.

In waterML 1.0, there is a divergence of mean between ODM, and WaterML.
WaterML only communcates the regularity, and the spacing of the observations (timeInterval). Whereas timesupport in the ODM is associated with the dataType, and time support. This will be addressed in 1.1
